<p>PURPOSE: To obtain a three-dimensional radar with high signal processing capability and processing efficiency by switching at two operating frequencies and improving the received state of a weak signal. CONSTITUTION: A three-dimensional image radar comprises a servo control system 18 for controlling an antenna, two radar transmitters for transmitting in two radar bands, a radar receiver for receiving a radar signal reflected in one radar band, and a digital signal processor 16 for processing a radar reflection signal, wherein the digital signal processor 16 includes an A/D converter 31, a Fourier transform processor 32, a coherent integrator filter 33, a detector 34 connected to the filter, a non-coherent integrator 35, a compatibility threshold value comparator 26, a buffer memory 37, a digital scanning converter 39 for converting given azimuth and angle of elevation direct angle signals to x, y, z addresses of a radar signal stored in the buffer memory, a computer 38 and a display 43.</p> |
